Method and apparatus for shaping of mats composed of loose fibers with a thermosetting resin interspersed throughout. The apparatus compresses the mat and exposes its laterally extending surfaces to elevated temperatures to obtain partial curing thereof. Slits are made in the surface regions adjacent areas where extra shaping will occur in forming the final product. These slits enable more precise shapes to be impressed upon the mat and eliminate the tendency of the partially cured areas to spring back to a position of lesser compression.

Disclosed is a method for making a board-like product capable of being formed into a duct section having a male end and a female end for joining sections together to form a duct. Inorganic fibers coated with a heat setable binder and collected in the form of a blanket are passed between heated moving surfaces to cure the binder in the top and bottom surface portions. The resultant partially cured blanket is then passed between one or more sets of heated platens to completely cure the binder and to shape the blanket to the desired thickness and configuration. A flat valley depression is formed longitudinally along the blanket down its center portion, and each edge is provided with a male edge, in the first set of platens. After the blanket has been shaped and cured, it is separated into two strips along the middle portion of the flat valley to form two strips, each having a female edge along one longitudinal edge and a male edge along the opposite edge. The method and apparatus of the present invention provides an improved female edge, i. e.
